CHIMNEY-CAP.

SPECIFICATION forming part of Letters Patent No. 417,415, dated December17, 1889.

Application filed August 16, 1889. Serial No. 320,965. (No model.)

Toall whom it may concern.-

Be it known that 1, WILLIAM E. ESPERSON, of Brooklyn, in the county ofKings and State of New York, have invented a certainnew and usefulImprovement in Chimney-Caps, of which the following is a specification.

My improvement relates to chimney-caps designed *for facilitating thedraft of-chiin- I will describe in detail a chimney-cap embodying myimprovement, and then point out the novel features in the claims.

In the accompanying drawings, Figure 1 is a vertical section of achimney-cap embodying my improvement. Fig. 2 is a transverse sectiontaken on the line a as of Fig. 1.

Similar letters of reference designate corresponding parts in both thefigures.

. A designates the deflectors. As shown more clearly in Fig. 2, each ofthe deflectors is approximately rectangular at its base and providedwith a horizontally-extendin g flange a. Inward of the flange a thedeflectors are, as shown, approximately conoidal in shape, and each hasa concave vertical exterior. They are all hollow, having open upper andlower ends, and the truncated upper end of one extends into the base ofanother.

The deflectors A are supported upon vertically-extending posts orpillars B, of which there are four represented. These .posts or pillarsare shown as bolts, and they extend through suitable apertures 19,formed in the deflectors A near the corners thereof and in the flange a.Surrounding the posts or pillars B, and arranged between the flanges aof the deflectors A, are tubes or sleeves O, which operate asspacing-pieces to maintain the deflectors A at proper relative distancesfrom each other. The upper ends of the posts or pillars B are providedwith heads 0, which may be nuts. Near the upper end of the cap is aplate D, which plate D is provided near its corners with suitableapertures, through which the posts or pillars B extend. The plate D isarranged between the heads 0 upon the posts or pillars B and the upperof the tubes or sleeves 0. Upon the lower end portions of 'the posts orpillars B are nuts (1. By tightening these nuts the deflectors A, thesleeves or tubes B, and the upper cap-plate D are firmly securedtogether. I have shown another plate E, extending over the upper end ofthe cap. This plate has its outer edges turned downwardly, as shown, andextends about the outer edge of the plate D. I have shown a means forsecuring the plates D and E together, consisting of a bolt F, passingthrough the same, with which engages an ornamental top G. The lower endportions of the posts or pillars B may be engaged with the upper end ofthe chimney in any suitable manner.

The deflectors A may, when made in the form shown or of approximatelysuch form,

be struck up from single pieces of metal in suitable dies. If, however,they are more or less pyramidal in shape, they may be made of separatepieces, secured togetherby rivets or otherwise.

It is to be observed that the deflectors A will in any event haveconcave vertical exteriors. This is very advantageous, because it causesthe wind striking them to be deflected upwardly with considerable force,and thus creates a strong draft up the chimney. It is also to beobserved that the cap is open upon all sides, and is thus free to beacted upon by the wind in whichever direction the latter may be blowing.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a chimney-cap, the combination, with supporting posts or pillars,of a series of hollow approximately-conoidal deflectors having openupper and lower ends, the truncated end of one entering the base ofanother, said deflectors being provided near their lower ends withhorizontally-extending flanges, through which said posts or pillarsextend and havin g vertically-concave exteriors, substantially asspecified.

2. In a chimney-cap, the combination, with supporting posts or pillars,of a series of hollow approximately-conoidal deflectors having openupper and lower ends, the truncated end of one entering the base ofanother, and thimbles or tubes surrounding said pillars or posts andoperating as spacing-pieces to separate said deflectors, said deflectorshaving vertically-concave exteriors, substantially as specified.
